The future of cryptocurrency

Are cryptocurrencies the future of international financial transactions? Can they be traded? Will the supermarket shopper use a digital currency to buy their groceries any time soon?

To answer those questions, it’s necessary to look at exactly what a cryptocurrency is.

Everyone is familiar with the concept of hard currency such as the dollar or the pound, which is issued by a central government. A digital currency such as bitcoin – the first, biggest and best known example – is ‘run’ by an opensource, peer-to-peer network.

Launched in 2008 by Satoshi Nakamoto and Martti Malmi, bitcoin is beyond the control of any single nation state and is effectively controlled by the world’s bitcoin users.

Blockchain

All cryptocurrencies make use of what is called distributed ledge technology, or ‘blockchain’ – a database in the cloud that is continuously updated and certified. Each new transaction creates a new block of data that is permanently locked and cannot be tampered with.

The word ‘cryptocurrency’ is derived from the complex cryptographic algorithms used to make transactions secure and completely anonymous. Unfortunately, that anonymity also makes it an ideal target for crime syndicates looking to launder their ill-gotten gains – one of its major detractions.

With bitcoin, the currency is generated by ‘miners’ using special software, who compete with each other to solve complex mathematical problems, for which they are paid with new bitcoins.

Anyone can set themselves up as a miner, from an individual using spare capacity on their home PC to companies with banks of servers doing nothing but mining.

Mining new bitcoins

Mining is the only way of generating new bitcoins, and is also designed to verify all bitcoin transactions. The work and reward involved give the currency an intrinsic financial value, while at the same time keeping the process secure and transparent.

The system is not without its flaws, however – not least that the huge amount of processing power required by miners consumes a huge amount of electricity to power and cool the specialised computers used by the big mining pools.

One alternative put forward by Elaine Shi, co-director of the Initiative for Cryptocurrency and Contracts (IC3), is that rather than generating a random number, the computing power is used to do something socially useful, such as gene sequencing.

Rising value

Bitcoin has increased dramatically in value. One Norwegian man bought 5,000 bitcoins in 2009 for just 150 kroner (£14) while writing a thesis on encryption. He then forgot about them until 2013, when having checked his bitcoin wallet, he discovered they were worth £468,000.

Bitcoin reached a peak value that year of $266. They then crashed to a low of $50 after the FBI seized 26,000 bitcoins held by a drug-dealer who was operating an eBay-style drug delivery service, taking advantage of bitcoin’s anonymity.

Bitcoin more than doubled in value over the 12 months from April 2016, rising from $417 to $1,026 in April 2017.

Cryptocurrencies are particularly suitable for international financial transactions that would normally be carried out using hard currencies such as the dollar. Already merchant banks such as JP Morgan Chase are rumoured to be investigating their use.

Rival cryptocurrencies

There are currently more than 700 different cryptocurrencies in existence, though only a handful had a market capitalisation in excess of $10m as of early 2017. The league table of market capitalisation looks like this:

Bitcoin ($17bn)

Ethereum ($4.6bn)

Ripple ($663m)

Dash $550m)

Litecoin ($326m)

In terms of size, Ethereum is the main contender to bitcoin, which has some technical question marks over its ability to cope with an increasing number of transactions.

Ripple is ‘pre-mined’, meaning it doesn’t have to be earned, and is positioning itself an alternative payment system for financial transactions, rather than a currency.

Litecoin, launched by Charles Lee, director of digital asset exchange Coinbase, is a proven, maths-based cryptocurrency seen by some as a dark horse to take the overspill if bitcoin gets to a technically unmanageable size.

Everyday transactions

Cryptocurrencies such as bitcoin and Ethereum are also being traded on the financial markets.

Attempts are being made to launch the world’s first Bitcoin exchange-traded fund (ETF). This will be a holding where you can buy and sell shares in a fund that owns a type of investment (such as property), without having to buy the underlying investment itself.

The bitcoin ETF is being proposed by the Winklevoss twins, who famously took out a law suit against Mark Zuckerberg, claiming they had originated the Facebook concept.

The ETF would hold bitcoins as a long-term investment, and investors would benefit from any increase in value. However, US regulator the Securities and Exchange Commission (SEC) turned down the initial application to launch the ETF in March 2017.

Bitcoin is also starting to be used for everyday transactions, rather than just cash transfers. Already major US retailers such as Amazon, eBay, PayPal, Apple, Dell, Kmart and Home Depot are accepting transactions in bitcoins.

However, many retailers are immediately converting bitcoins into dollars using a middleman to avoid some of the currency’s historically wild fluctuations.

What is the best cryptocurrency to invest in? Predictions for Block chain 2018

2018 has already been called the “The Year of the Altcoins”. In a hunt for a new Bitcoin, let’s try to distinguish 3 macro trends for cryptocurrencies during the next 12 months.

The mother of all cryptos will lose its throne

It is highly questionable whether Bitcoin will manage to keep its market share. Crypto experts believe there is a good chance its network value will be overtaken by another cryptocurrency. Bitcoin has a number of challenges to tackle: transaction costs, scalability and problems with the centralization of its mining. The question is, if Bitcoin sunk into oblivion, which crypto would become the market leader? For now, it looks like Ethereum is gaining ground, intending to become the top “altcoin” of the year.

dApps gaining traction

Decentralised applications (dApps) are constantly becoming more popular. Today, there are 910 dApps that are built on Ethereum alone. These apps presuppose various applications, including payments and lending, tokenisation of assets, gambling, insurance — the opportunities are endless. Its time to see what Blockchain can propose aside from payments.

Scalability becomes a cornerstone

With the exponential growth of transactions made on the Blockchain over the past year, the issue of scalability with more popular Blockchains, such as Bitcoin and Ethereum, has arisen. Even though Ethereum has proven it can handle 1 mln transactions per day, this still won't be enough with the flood of dApps coming. Various Blockchain protocols aim to solve the scalability problem, maintaining security, and decentralisation. Let's see whether they will succeed.

One thing is for sure – in a digital age and an increasingly cashless society, cryptocurrencies look set to have a growing influence on every aspect of our lives.
